$- 2 n - 3 = 5 n - 7 n$

Step 1

Since $n$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$5 n - 7 n = - 2 n - 3$

Step 2

Subtract $7 n$ from $5 n$ .

$- 2 n = - 2 n - 3$

Step 3

Move all terms containing $n$ to the left side of the equation.

Step 3.1

Add $2 n$ to both sides of the equation.

$- 2 n + 2 n = - 3$

Step 3.2

Add $- 2 n$ and $2 n$ .

$0 = - 3$

Step 4

Since $0 \neq - 3$ , there are no solutions.
